无法连接到本地azure cosmosdb仿真器

Question

我在Win10计算机上安装了Azure CosmosDB Emulator，并且可以看到启动页面：

但是当我尝试通过Robo3T或命令行连接到数据库时，它不起作用。我使用以下cmd：

mongo mongodb://localhost:foofoojf5%2FR%2Bob0N8A7Cgv30VRDJIWEHLM%2B4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw%2FJw%3D%3D@localhost:10255/admin?ssl=true

我遇到了以下问题：

  

2019-07-18T14：33：27.265 + 0200 W网络[thread1]在5000ms毫秒后无法连接到127.0.0.1:10255，放弃了。   2019-07-18T14：33：27.266 + 0200 E查询[thread1]错误：无法连接到服务器localhost：10255，连接尝试失败：   connect@src/mongo/shell/mongo.js：237：13   @（连接）：1：6   例外：连接失败

它在本地，所以我认为没有端口问题。

我用ROBO3T工具连接了mongo模拟器，请参阅我的配置。

首先，从此link获取仿真器连接字符串。

  

mongodb：// localhost：C2y6yDjf5 / R + ob0N8A7Cgv30VRDJIWEHLM + 4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw / Jw == @ localhost：10255 / admin？ssl = true

然后创建连接配置：

身份验证：

SSL：

就我而言，要与用于MongoDb的Azure CosmosDb API进行交互，我们需要在％localappdata％\ CosmosDbEmulator下创建一个专用的新文件夹，并启用MongoDb端点v3.6（请参见以下步骤1中的PowerShell命令< / strong> ）。

注意： 出于任何原因，如果将CosmosDb仿真器重置为默认文件夹路径％localappdata％\ CosmosDbEmulator（或）在Robo 3T中无法连接 然后始终在步骤1 中再次执行以下PowerShell脚本。

注意： 从Robo 3T v1.4开始，我们没有SSL标签 设置对话框。相反，我们有一个TLS标签。

1. Download and install Azure CosmosDb Emulator from https://docs.microsoft.com/en-us/azure/cosmos-db/local-emulator?tabs=powershell%2Cssl-netstd21
2. Download and install Robo 3T (1.4.2 or latest) from https://robomongo.org/download
3. To show Azure CosmosDb emulator related database(s) in Robo 3T client app

Step 1
- Launch Azure CosmosDb Emulator 
  (Optional: Just to check CosmosDbEmulator is started successfully)
- Open Powershell as administrator and execute below commands

  # PowerShell Script
  # Change directory to default location where CosmosDb emulator is installed.
  cd\
  cd '.\Program Files\Azure Cosmos DB Emulator\'
             
  # [Optional] If any cosmosDb emulator instance is running then shutdown
  .\Microsoft.Azure.Cosmos.Emulator.exe /shutdown
        
  # To interact Azure CosmosDb API for MongoDb, create a new folder "<MongoDb>" under 
  # %localappdata%\CosmosDbEmulator and enable MongoDb endpoint v3.6
  .\Microsoft.Azure.Cosmos.Emulator.exe /DataPath="$env:localappdata\CosmosDBEmulator\MongoDb" /EnableMongoDbEndpoint=3.6

Step 2      
- Now CosmosDb emulator will be successfully started,
  and launches the URL https://localhost:8081/_explorer/index.html in the browser
- Note down MongoDb connection string details from browser which will be required 
  while creating new Robo 3T connection. The default MongoDb connection string format is 
  mongodb://username:password@host:port/[database]?ssl=true
    - Username: localhost
    - Password (Primary Key): C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==
    - Port: 10255
    - Database: admin
    
Step 3
- Launch Robo 3T
- Click on Create new connection 
- In "Connection" tab
    - Provide Name of the connection as "<CosmosDbEmulator>"
    - Add port number as 10255
        
- In "Authentication" tab provide details noted down in previous Step 2
    - Check "Perform authentication"
    - Add Database as "admin"
    - Add Username as "https://localhost:8081"
    - Add Password as "C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw=="
        
- In "TLS" tab provide
    - Check "Use TLS protocol"
    - From Authentication Method dropdown select "Self-signed Certificate"
        
- Click on "Test" button. 
    - It should successfully connects to localhost:10255 via TLS tunnel
    - It should successfully authorise to database "admin"
    
- Click on "Save" button    
- Click on "Connect" button. 
    - It will show the admin database and its related collections.
